Endodontic therapy (a root canal) is usually performed on patients where the cause of their dental pain is from the inflammation or infection of the tissues in the nerve chamber of the tooth. This process commonly occurs when bacteria sneaks its way into the nerve chamber of the tooth. A neglected tooth is prime suspect for tooth decay to start.

Other reasons for performing a root canal are a fracture of a tooth that has led to the exposure of the nerve chamber or a tooth with dead or dying tissue in the nerve chamber from chronic trauma to the tooth.

This process is usually done because of the reasons listed above. After a dose of anesthesia is established, any decay and old restoration is removed so that the tooth can be evaluated to see if it is restorable.  Once the tooth is determined to be able to be restored, an access into the chamber of the tooth is established.  All the tissue including the nerve, blood supply, and associated bacteria is removed from the chamber.  The goal is to reestablish a sterile environment in the tooth.

Root canal therapy is routinely done in two appointments.  If this is the case, medication is place in the tooth to help reduce the infection that maybe in the surrounding structures of the tooth.  On the second appointment, the tooth is cleaned out again and if the tooth is in good shape, it is then sealed to help prevent reinfection of the chamber.  A crown, which is discussed on the restorative page, is placed to support the tooth.


On occasion, the initial root canal can become infected. If this happens, the tooth is evaluated for potential causes and if determined the old filling material is the source, it may be removed and a new sealer placed. If a crown is present, the access opening is usually established through the crown and a composite is placed following the retreatment.


Occasionally the source of infection cannot be cleaned out from an access through the crown.  If this is the case, the patient is set up for endodontic surgery.  On the day of the surgery, the patient is anesthetized and the bone adjacent to the source of infection is exposed.  A minimal access through the bone is established, the infection is cleaned out, and the canal is sealed at the tip of the root.  The majority of the time, this procedure is done by an endodontist.
